New target species - Leafminers

We haven't had a new target species for a while, and with Cheilosa fasciata, Millium effusum, and Zimmermannia liebwerdella leaving the target list soon I thought I'd add a few new ones. Leafminers are a very under-observed group in Germany, so those might be a good fit for
our project. Here are a few fairly distinctive ones to start with:

1. https://www.inaturalist.org/taxa/715391-Agromyza-nigrescens
This species mines on Geranium sp. (I've seen them most on G. molle), here's a link with more information: https://bladmineerders.nl/parasites/animalia/arthropoda/insecta/diptera/brachycera/agromyzidae/agromyzinae/agromyza/agromyza-nigrescens/

2. https://www.inaturalist.org/taxa/339405-Phytomyza-ranunculi
This species can often be found on Ranunculus, Anemone, and Ficaria verna, and can be distinguished from the similar Phytomyza ranunculivora through; "frass grains fine, separated by less than their diameter, often also fusing into pearl strings". Here's a link with more information: https://bladmineerders.nl/parasites/animalia/arthropoda/insecta/diptera/brachycera/agromyzidae/phytomyzinae/phytomyza/phytomyza-ranunculi/

if you make any leafmine observations (some of you do already), I would really Appreciate it if you add them the Leafminers of Europe project on iNat.

Happy iNatting, and good luck finding some leafmines,
Alexis (@alexis_orion)

A Call to Grass

Hi everyone,

I stumbled over this observation https://www.inaturalist.org/observations/28990168 of Cynosurus cristatus yesterday, which @bobwardell helped to identify. In checking the stats on the taxa page https://www.inaturalist.org/taxa/76581-Cynosurus-cristatus I found that we have only 12 observations in Germany so far, though wikipedia says it is a quite common grass, though locally listed as endangered. But looking at the GBIF data points in the map, it seems it should not be so difficult to get some more observations of it at iNat, though it seems to be advantageous to explore in Bavaria.

Digging a bit further in Poaceae it seems that many grass species are way too overlooked in general.

Poaceae observations in Germany: ~ 3000 observations with 161 different species sounds maybe not to bad. But a big chunk of them are not surprisingly Phragmites australis (266) and some others, and many, I assume, unidentified deeper than Poaceae:
https://www.inaturalist.org/observations?locale=de&place_id=7207&preferred_place_id=7207&subview=grid&taxon_id=47434&view=species

So I would like to give a Call to Grass for some of them (completely arbitrarily chosen ;-), their visuals seem catchy enough to remember them), which hopefully raises other Poaceae observation counters as well.
- Crested Dogstail (Wiesen-Kammgras), https://www.inaturalist.org/taxa/76581-Cynosurus-cristatus, currently 12 observations
- European Feather-grass (Echtes Federgras), https://www.inaturalist.org/taxa/355674-Stipa-pennata, currently 2 observations
- King Ranch bluestem (Finger-Bartgras), https://www.inaturalist.org/taxa/75842-Bothriochloa-ischaemum, currently 2 observations
- Blue Moor-grass (Kalk-Blaugras), https://www.inaturalist.org/taxa/363774-Sesleria-caerulea, currently 4 observations
- Giant Fescue (Riesen-Schwingel), https://www.inaturalist.org/taxa/162949-Festuca-gigantea, currently 11 observations
- Wood Millet (Waldhirse), https://www.inaturalist.org/taxa/165390-Milium-effusum, currently 18 observations

Any additions to the list, especially from a more expert point of view, are welcome!

Happy exploring!
Monika

Two new target species

Hi and happy new year to everyone,

just as a short note, we've added to new target species in the last weeks:

1) https://www.inaturalist.org/taxa/430143-Boreus-hyemalis
Informations about it (in german): https://www.insekten-sachsen.de/Pages/TaxonomyBrowser.aspx?id=223691
Can be found:
- on mosses: Hylocomium splendens, Pleurozium schreberi, Hedwigia albicans, Polytrichum piliferum and Grimmia sp.
- from October til March

2) https://www.inaturalist.org/taxa/156527-Pottia
- lives very short time and is very tiny
- only 3 iNat records so far
- how does it look like? Check out this obs by alexis_orion: https://www.inaturalist.org/observations/37188499
- it is now part of Tortula (https://www.inaturalist.org/taxon_changes/68776)

Cheers

New target species

Hi Everyone!
nobody has found a Pionosomus varius for a while, so I think it's time to choose a new target species.
@carnifex suggested in https://www.inaturalist.org/observations/32838192 that I could try and find a Similar Fruit Fly (Drosophila simulans), and I thought that would be a good next target. D. simulans looks very similar to D. melanogaster, and a good photo of the abdomen of a male is needed for a species ID. @carnifex could go through our Drosophila observations to help find photos of D. simulans. Here's the best iNat photo of that species, to give you an idea of what they look like:

I've also got a question for the members of this project; Should we leave the Pionosomus varius challenge open, and have this as a second challenge at the same time, or should we close the other one down?

Good luck finding a Drosophila simulans,
Alexis

Ant's-nest Cricket Winner / Ameisengrillen Gewinner

The winner of the Ants'-nest Cricket (Myrmecophilus acervorum) challenge is this individual found in Berlin by @alexis_orion on August 9, 2019.
--------------------------------------------------------------------------------------------------------------
Der gewinner der Ameisengrillen (Myrmecophilus acervorum) Challenge ist dieses exemplar, was am 9. August 2019 von @alexis_orion in Berlin gefunden wurde.
--------------------------------------------------------------------------------------------------------------
The next challenge is to find a Pionosomus varius. The next person to post one of these on iNat from Germany can choose the next species for us to look for.
--------------------------------------------------------------------------------------------------------------
Die nächste Aufgabe ist die Suche nach Pionosomus varius. Wer als nächstes eine Beobachtung von P. varius mit Fundort in Deutschland auf iNat veröffentlicht, darf die nächste Art auswählen, nach der gesucht werden soll.
--------------------------------------------------------------------------------------------------------------
Happy iNatting, and good luck finding a Pionosomus varius
Frohes iNatten und viel Glück bei der Suche nach Pionosomus varius

-Alexis
